(54)	Viscous liquid-dispensing container

(57) A viscous liquid-dispensing container which allows almost all amount of the content thereof to be easily extracted. The container includes a liquid-dispensing section (1) having a head (2) and a shoulder (3), and inner and outer containers (14, 17) respectively connected with the shoulder (3). The liquid-dispensing section (1) includes a first check valve (7) for allowing only extraction of the liquid. The outer container (17) includes a second check valve (21) for allowing only introduction of the exterior air. The inner container (14) for accommodating the viscous liquid has a upper sleeve (16) and lower bag (15) connected to the upper sleeve (16). The upper sleeve (16) is relatively hard, while the lower bag (15) is made of a flexible thin film. After a predetermined amount of liquid is extracted, the lower bag (15) is inverted and invades into the upper sleeve depending on the reduction of the liquid in the inner container (14).
